We present two ways (instantaneous and cumulative) to transform bibliographic networks, using the works’ publication year, into corresponding temporal networks based on temporal quantities. We also show how to use the addition of temporal quantities to define interesting temporal properties of nodes, links and their groups thus providing an insight into evolution of bibliographic networks. Using the multiplication of temporal networks we obtain different derived temporal networks providing us with new views on studied networks. The proposed approach is illustrated with examples from the collection of bibliographic networks on peer review.  相似文献

Mothers who use substances need integrated, multi-sectoral intervention services to support substance use discontinuation. We explored mothers’ service use at Breaking the Cycle, an early intervention and prevention program for pregnant and parenting women and their young children in Toronto, Canada. We conducted retrospective analyses of families’ service records and client charts (N = 160). Aims were to 1) describe women’s use of service, 2) examine how early engagement of pregnant women related to postnatal service use, and 3) examine the circumstances in which women ended their service relationship with Breaking the Cycle. Specifically, we examined circumstances at service ending relating to women’s service goals; custody status with children; and global substance-use, parent-child relationship, and child development outcomes. We found that these vulnerable women were actively engaged in many services and for a long duration, early engagement was associated with greater service use, and greater service use was associated with more positive circumstances upon ending service. Results provide support for a relational approach to service that promotes not only the relationship between mother and child, and mother and service provider, but also highlights relationships among staff, between staff and management, and between community partners as integral to effective service delivery. Integrating positive relationships at all levels is critical to support vulnerable families with complex needs.  相似文献

Partnership in higher education emphasises an active role for students in both teaching and learning. This pedagogical culture is likely to make students assessment literate and engage them in deep learning. In this study, Iranian students experiencing learning-by-teaching (LbT) in private language institutes were interviewed to compare their perceptions toward assessment and learning with their counterparts without this experience. Findings show that LbT fosters students’ assessment literacy and deep learning. Results also reveal that by teaching other students, quasi-teachers promote a broader understanding of assessment and grade practices in comparison to other students. Unlike their counterparts, quasi-teachers de-emphasised grades and showed a greater focus on learning. Moreover, explaining the materials to other students provided them with a deeper cognitive process resulting in deeper learning. These results underscore the perceived importance of partnership in higher education.  相似文献

This study is a comparative analysis of the characteristics of moral exemplars presented in moral education textbooks in Korea and Japan. The purpose of the study is to examine and compare moral values presented through the lives and stories of moral exemplars in the two countries that have moral education as an independent and separate subject based on the national curriculum. To this end, the study uses analytical criteria such as gender, nationality, social roles, historical backgrounds, and specific moral values in order to investigate characteristics of 307 moral exemplars in Korea’s and Japan’s most used moral education textbooks. The results show significant similarities and differences in moral exemplars between the two nations. In the case of the similarities, both countries emphasize moral autonomy and respect for human life. In the case of the differences, while Korea presents more historic figures as moral exemplars, Japan presents more students and ordinary people as moral exemplars.  相似文献

The high rate of academic dishonesty reported among Chinese college students has created challenges for practitioners in both domestic and Western universities. Following two contrasting yet complementary scholarly approaches, this study explored the relative importance of predictors indicative of students’ intention to cheat (moral attitude, subjective norm and penalty enforcement) and of their educational preparedness for academic integrity (integrity engagement) in explaining academic dishonesty, with an emphasis on gender differences. We administered a questionnaire survey to a sample of 2009 Chinese undergraduate students. The results indicated that moral attitude and integrity engagement were the major predictors, that subjective norm accounted for marginal variations of academic dishonesty, and that the influence of penalty enforcement was insignificant. Some gender differences on both the mean score and effect levels of the four predictors were revealed. The effects of grade, year and area of study on academic dishonesty (and particularly their joint effects with gender) were noteworthy. These findings are discussed relative to the results of prior studies and the Chinese context.  相似文献

This study explores the use of a corpus of classroom discourse data (Singapore Corpus of Research in Education or SCoRE) to facilitate the professional development of English language (EL) teachers in Singapore. A survey was first conducted to probe the knowledge base and belief system of EL teachers in three key domains: epistemology, pedagogy, and discourse. This was followed by a discourse analysis of the SCoRE corpus to mine resources that could address the specific professional needs of teachers identified through the survey. Survey findings suggest that EL teachers in Singapore are less secure in epistemology than pedagogy or discourse-related issues. The efficacy of using corpus-based materials to help teachers reflect on and develop their professional competencies was tested through a workshop. The paper concludes with a discussion of the implications of using authentic and situated corpus resources to facilitate teachers’ reflective practice and professional development.  相似文献

Analyzing 219 blog posts from 52 self-employed women lifestyle bloggers in North America, this study shows how these digital professionals navigate tensions and communicatively constitute work flexibility. In their narratives, women bloggers employed tension management approaches such as reframing, continual connections, and reflective practice in response to tensions in enacting temporal–spatial, identity, and financial flexibility. Specifically, women followed oxymoronic constructions – disciplined freedom, branded authenticity, and dependable independence – to embrace and transform competing poles of fluidity?structure, authenticity?marketability, and independence?interconnection. Expanding work–life research to the self-employed digital labor context, this study responds to recent calls to uncover more-than tension management strategies in empirical settings and contributes to a tension-centered, contextual, and processual analysis of workplace flexibility construction.  相似文献

Drawing on kindergarten teachers’ and University departments’ reactions to the Greek government’s initiative to adopt an integrated Early Childhood Education and Care (ECEC) system, the present study aimed to explore how various ECEC professional groups working in the two main preschool programs operating in Greece define different aspects inherent to ECEC theory and practice. Results yielded both similarities and differences, with aspects of health and well-being characterized mostly as having both a ‘care’ and an ‘education’ aspect, whereas personal and professional development and communication, management and administrative factors were characterized as educational in nature. Discrepancies were revealed in terms of child development, education and play and social environment factors, with those working in childcare settings defining them as including both ‘care’ and ‘education’ whereas those working in kindergartens defined them as educational in nature.  相似文献

随着Web服务数量的急剧增长,如何在大量功能相似但非功能属性各异的服务中选择满足用户个性化需求的服务是亟需解决的问题。基于QoS(Quality of Service)预测的服务推荐方法成为研究热点。然而, QoS数据的稀疏性和“冷启动”问题阻碍其发展。针对当前主流的QoS预测模型预测精度不高和收敛速度较慢等问题,提出一种基于随机游走模型和矩阵分解技术的混合QoS预测方法。该方法首先基于矩阵分解获得用户及服务的潜因子矩阵,并将用户潜因子矩阵转化为用户相似度矩阵;然后基于用户相似度矩阵并结合Web服务的网络位置信息,使用随机游走模型提高用户相似度矩阵的准确性;最终结合协同过滤方法与矩阵分解模型进行QoS预测。在真实数据集上实验,结果表明,与当前主流的QoS预测方法相比,该方法具有更高的预测精度和效率。  相似文献
